Service Broker教程 - 一臺機器上有兩個SQL Server實例。如何路由？

Question

我正在關注MSDN的Completing a Conversation Between Instances教程。該Lesson 2: Creating the Initiator Database（末）顯示，如何在引發位點創建航線（縮短）：

... 
USE InstInitiatorDB; 
CREATE ROUTE InstTargetRoute 
WITH SERVICE_NAME = 
     N'//TgtDB/2InstSample/TargetService', 
    ADDRESS = N'TCP://MyTargetComputer:4022'; 

... 

USE msdb; 
CREATE ROUTE InstInitiatorRoute 
WITH SERVICE_NAME = 
     N'//InstDB/2InstSample/InitiatorService', 
    ADDRESS = N'LOCAL' 

和Lesson 3: Completing the Target Conversation Objects確實目標實例相同：

USE InstTargetDB; 
CREATE ROUTE InstInitiatorRoute 
WITH SERVICE_NAME = 
     N'//InstDB/2InstSample/InitiatorService', 
    ADDRESS = N'TCP://MyInitiatorComputer:4022'; 

... 

USE msdb 
CREATE ROUTE InstTargetRoute 
WITH SERVICE_NAME = 
     N'//TgtDB/2InstSample/TargetService', 
    ADDRESS = N'LOCAL'; 

然而，教程假設SQL服務器實例在單獨的硬件上運行。如果兩臺SQL服務器實例在同一臺計算機上運行，​​我應該如何更改路由或其他什麼？

Answer 1

這兩個實例不能共享偵聽器端口。在第1課，你有這樣的：

... 
CREATE ENDPOINT InstTargetEndpoint 
STATE = STARTED 
AS TCP (LISTENER_PORT = 4022) 
... 

和第2課，你有這樣的：

... 
CREATE ENDPOINT InstInitiatorEndpoint 
STATE = STARTED 
AS TCP (LISTENER_PORT = 4022) 
... 

既是實例被配置爲偵聽同一TCP端口上這是行不通的。必須有所不同。讓我們使目標監聽4023：

... 
CREATE ENDPOINT InstTargetEndpoint 
STATE = STARTED 
AS TCP (LISTENER_PORT = 4023) 
... 

然後從發起到目標的路線具有指定端口現在4023：

... 
CREATE ROUTE InstTargetRoute 
WITH SERVICE_NAME = 
     N''//TgtDB/2InstSample/TargetService'', 
    ADDRESS = N''TCP://MyTargetComputer:4023'';'; 
... 

其他一切保持不變。
